Parameters
- Q:Can solar panels be used for off-grid living?
- Yes, solar panels can be used for off-grid living. They are a popular and sustainable option for generating electricity in remote areas or locations where there is no access to the traditional power grid. Solar panels collect energy from the sun and convert it into usable electricity, which can power various appliances and systems in an off-grid home. Additionally, by incorporating batteries or other energy storage solutions, solar panels can provide a consistent power supply, even during periods of low sunlight or at night.
- Q:Me and my friend have made our own functional solar panels for considerably less than retail prices and we are thinking about selling them. Are there any legal issues regarding this? Would I need any special licenses or anything? Would using brand name components or parts in the panels make any difference legally? I want to know before I just go out and start doing it. Thanks!
- They are your property. If you want to sell them, have at it. Of course, as soon as the government sees you making some money, they will descend on you like hyenas for ;their 'share'. If you apply and get a 'commercial' permit, they will be in you pocket in a flash. The government will steal anything they can get their hands on. They use 'zoning laws' to carry out their ruse. Then they call themselves your 'partner'. Same as the mafia does. They have a lot of worthless bureaucrats that want somebody else's money. In California, most of the government workers seem to be communists. They hate business and are extremely jealous of any entrepreneur. They think they are experts on Fair business Practices. Most of them have never worked an honest days work in their life. Let alone think up an idea such as yours.
- Q:i have 2 questions.. I have a 6v solar panel, if i wanted to charge batteries with that it what batteries could i charge? Could charge normal AA batteries with it our do i need special batteries.2. I have a 6v solar panel that produces watt. I want to light a bulb with it but whenever i hook it up the solar panel won't light it up. I think the current of the solar panel is too low. How can i increase the current of the solar panel
- [] Use it to charge 4 pieces AA cell ( connect in series to make 5V battery pack ) for 0 to 4 hours. Good for cell rated 600mAH ,2000mAH,2500mAH. [2] Cannot increase current. Buy some more this panel and hook them together in parallel to increase current. You need at least ten pieces to make current reaches .6A to light up some 6V bulbs.
- Q:is this fact true? - its a limitation to solar panels during summer when it's in extremly hot countrie. I've heard it from my science teacher .. please give detail if you have any and any more benefits/limitations is welcomed .. Thank you :) !
- i couldn't see any evidence of that on the internet, but i only searched for a little while for ya. all i can say is in Australia 40 - 50 degrees celcious is about our hottest, and i have never heard of it being a problem. im sure that being the sunburnt country we would know as general knowledge if the solar systems didn't go well if it was too hot.
- Q:How long does it take to recoup the investment in solar panels?
- The time it takes to recoup the investment in solar panels varies depending on several factors, such as the cost of the panels, the amount of energy they generate, the electricity rates, and any available incentives or tax credits. On average, it can take anywhere from 5 to 15 years to recover the initial investment. However, with decreasing panel costs and increasing energy savings, the payback period is becoming shorter, making solar panels a more attractive and financially viable option for many homeowners and businesses.
- Q:are there solar panel that work without the sun?
- No. Solar literally means Sun. But...scientists are working on a panel that can absorb energy after the sun has set. It may be years until we see any commercial success.
- Q:why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.
- Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
- Q:I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world''
- Wood? Steel tubing could be a lot lighter. Use the hardest narrowest tires you can find bicycle wheels and tires would work nicely and they can be had with really light disc breaks. As for a motor a golf cart motor is made to order. You can get an old electric golf cart and have almost all the parts you will need. Hell cover the roof of the cart with photo voltaic and have a ball. Note I stress weight savings as weight will cost you energy and with photos you won't have much to spare. You will need a battery pac of some sort lithium are a better choice than lead acid. there is a ton more to consider good luck with your project.
- Q:How much energy can be generated from a solar panel on a clear, bright summer's day for example?
- it depends on the size of the panel and if it is installed in an optimal location. there are many 00W panels commercially available and they can be ganged for a number of different output configurations.
- Q:Any recommendations for companies? Any things to look out for?
- Yes, solar panels are a great way to save on electricity costs for your home. 4 things I can tell you to look out for are: Make sure you can fit enough solar panels on your house to make a decent saving. If you don't have the roof space then you can't put up enough panels and you might as well not bother. For a medium sized home, I would say that you should go no smaller than 2.2kW in solar panels. If you can fit more then go for it. Make sure that the inverter that is used is big enough. It has to deal with the watts from the solar panels back to the power board to convert it as useable energy. If you have a rebate system where you live then make sure you use it. Where I am we have carbon credits that the government will give you that you use to offset the cost of purchasing solar. Don't fall for gimmicks where a company will promise you that you won't pay electricity every again. In order for that to happen you need to be putting more electricity back in the grid as you are currently using so you either need a huge amount of solar panels or you really need to cut back on what you are currently using.
